This still of the Earth with clouds is intended to be wrapped to a sphere. The look (i.e., appearance of the clouds, coloration of the ocean, etc) was art-directed to meet the needs of a particular production.This visualization was created in support of the Science on a Sphere film called "Largest" which is about Jupiter. This still image matches several other Earth apperances from the film. Note: Flat Earth still. Animator: Greg Shirah (NASA/GSFC). Editor: Victoria Weeks (HTSI)....

Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before. Starting with our camera high above the Earth, we rush in towards the surface at what would be an impossible speed for any known vehicle.

The Chesapeake Bay Landsat-7 Mosaic is a composite of eight Landsat-7 scenes acquired during the period of 1999-2002, where each pixel represents about 15 square meters on the ground. The original data set was a false-color Landsat-7 (ETM+) image using bands 7,4,2 and the panchromatic band (8). Color correction has been applied to resemble natural looking colors.This page offers the full color-corrected data set for download and lets you look around at it using the online viewer. You can...

A tiny neutron star orbits incessantly around a massive star with a diameter a million times larger than its own. The high luminosity of the massive star drives a strong wind from its surface. The neutron star crashes through this wind at over 300 kilometers per second. The gravity and X-ray luminosity of the neutron star act to disrupt the wind, producing an extended wake of dense gas trailing behind the neutron star. This simulation, in the reference frame of the neutron star, shows...

NASA's Aqua satellite was launched on May 4, 2002 with six Earth-observing instruments on board. Aqua circles the Earth every 99 minutes and is in a polar orbit, passing within ten degrees of each pole on every orbit. The orbit is sun-synchronous, meaning that the satellite always passes over a particular part of the Earth at about the same local time each day. Aqua always crosses the equator from south to north at about 1:30 PM local time. One of the instruments on Aqua, MODIS, measures 36...

The animations range from real-time, in which no rotation can be perceived, to 3600 times real-time, in which both the Earth's rotation and cloud motion can bee seen. The series also includes an animation in which the Earth's rotation...

NASA's TRMM spacecraft observed this view of Hurricane Ike on September 12, 2008 at 1035Z or 6:35 AM EST. At this time the storm was an extremely dangerous category 2 hurricane with sustained winds of 90 knots (103 mph) and a pressure reading of 953 millibars. Hurricane-force winds were extending outward 120 miles from the center, while tropical storm-force winds extend up to 275 miles. Size matters when it comes to hurricanes. Larger storms produce a wider swath of wind damage and stir up the...

Satellite data can gauge the health of plants, which is a good indicator of drought. Satellite imagery shows changes in vegetation between 1999 and 2003. The Normalized Difference Vegetation Index (NDVI) measures how dense and green plant leaves are, which suggests overall vegetative health. The NDVI images are also useful as a measure of drought when compared to 'normal' plant health.

Using data from different spacecraft and some powerful computer technology, visualizers at the Goddard Space Flight Center present you with a collection of American cities in a way you have never seen them before.

RODEO AND CHEDISKI FIRES IN ARIZONA - On June 21, 2002, the Rodeo and Chediski Fires in east-central Arizona were still two separate fires. This true-color scene from the Enhanced Thematic Mapper Plus aboard the Landsat 7 satellite shows the massive quantities of smoke streaming northward from the fires, which are burning about 100 miles east-northeast of Phoenix. The smaller Chediski Fire is on the right, and the Rodeo Fire is on the left. Over the weekend of June 22, the two fires merged into...

Here is a close-up view of dark 'tentacles' or 'tadpoles' moving towards the solar surface in this solar flare of April 21, 2002 seen by TRACE. One theory proposed in this press release is that they are due to voids created by magnetic reconnection in the flare. This version of the visualization displays the instrument clock time tags.

These figures have been adjusted to match United Nations totals. The most dramatic differences in population are not readily visible in this animation because they are located in cities. The maximum population density in 1990 was about 79,000 people per square kilometer, while the estimated maximum population density in 2015 will be about 236,000...
